DESCRIPTION:
Herbert Scott / Ever Ready Specialties Co., London, a rare model EP4 electromagnetic mantel timepiece, the arabic numeral white enamel dial with blued steel hands mounted to a decorative nickelled plate, and supported by two hollow nickel plated columns housing the batteries, brass movement with two wheel train, the pendulum with unusual knife edge suspension and cylindrical brass bob, swinging front to back between the columns, and receiving periodic impulse from an electromagnet, all on an ebonized oblong base with adjustable brass feet, level, and conforming dome, the underside with two paper labels giving the model number and instructions for ordering replacement batteries, serial #1007
CONDITION:
very good overall, nickel plating very good, inside of columns with minor corrosion and verdigris, dial with a few minor scratches, hands with minor pitting, pendulum rod thread with scattered specks of oxide, bob and indicator good, base good, one label with significant losses, the other nearly intact, dome with small chip at bottom edge, not running. Herbert Scott (1865-1943) was born in Bradford, Yorkshire, England. In 1902 he secured a patent for the mechanism used in this clock. A variation on Hipp's toggle, there are V notches at the tips of all escape wheel teeth, and a pivoted, L shaped trailer at the top of the pendulum rod. Following impulse, the trailer gathers the escape wheel teeth one at a time, thereby steadily advancing the hands. The pendulum amplitude eventually falls to a point where the trailer will no longer gather another tooth, and comes to rest in the V notch at a tooth tip. A projection on the trailer now is in line with the contact, and closes the circuit, thereby energizing the magnet, and providing impulse to the pendulum.
